NETA Level 2 Certified Assistant Electrical Testing Specialist Sample Questions (Q78-Q83):

NEW QUESTION # 78
According to NETA standards, what is themaximum allowable timetest instruments may remain in service before requiring recalibration?

Answer: A

Explanation:
NETA standards require test instruments to be calibrated at leastonce every 12 monthsto ensure measurement accuracy and traceability. Using out-of-calibration instruments can invalidate test results and compromise safety decisions. NETA Level 2 technicians must verify calibration labels, dates, and traceability before using any test equipment in the field.


NEW QUESTION # 79
Polarization Index (PI) is defined as the ratio of insulation resistance measured at:

Answer: B

Explanation:
Polarization Index evaluates insulation quality over time and is calculated as:
PI = IR at 10 minutes ÷ IR at 1 minute.
NETA Level 2 technicians use PI testing to assess insulation dryness, cleanliness, and aging.


NEW QUESTION # 80
Electromotive force (EMF) is measured in:

Answer: A

Explanation:
Electromotive force represents electrical potential difference and is measured involts. NETA Level 2 technicians encounter EMF when evaluating generators, transformers, batteries, and induced voltages during testing and commissioning activities.


NEW QUESTION # 81
A delta-connected load has aphase impedance of 12 #and is supplied from a480 V line-to-line source. What is theline current?

Answer: A

Explanation:
For delta systems:
Phase voltage = Line voltage = 480 V
Phase current = V / Z = 480 / 12 = 40 A
Line current = #3 × Phase current
= 1.732 × 40 #69.3 A
NETA Level 2 technicians must correctly distinguish between phase and line quantities when evaluating three- phase systems, as incorrect assumptions frequently lead to misinterpreted test results.


NEW QUESTION # 82
What is the distance between points (3,5) and (4,5) on a rectangular coordinate grid?

Answer: C

Explanation:
The distance between two points with the same y-coordinate is the absolute difference in their x-coordinates.
|4 # 3| =1. NETA Level 2 technicians must demonstrate basic math skills for interpreting diagrams, test plots, and graphical data.


NEW QUESTION # 83
......
